Oregon Heritage, which includes the State Historic Preservation Office, manages some database and mapping resources that can assist you with your research or projects.
The Survey and Inventory program maintains the Oregon Statewide Inventory, a publically-accessible database of all built properties for which the SHPO has collected physical and/or historical information. While the Statewide Inventory does include the most recent evaluation for eligibility for listing in the National register of Historic Places, mere inclusion in the Statewide Inventory is not an official designation of any kind. The Inventory will, however, indicate if a property has been officially designated, by listing in the National Register of Historic Places, or determined to be eligible for listing by the National Park Service.

The Oregon SHPO hosts and administers the Oregon Archaeological Records Remote Access (OARRA). A GIS based web portal with information on documented archaeological resources and archaeological survey reports.
